BRUSH-TYPE SKIRT
A brush-type skirt surrounds the abrasive pad and it
serves two purposes: (1) it extends below the surface
of the abrasive pad so that it contacts the work sur -
face first. This positions the sanding head parallel to
the work surface, before the abrasive contacts the
work surface, preventing the abrasive from “gouging”
the work surface. (2) it also helps contain the drywall
dust until the vacuum cleaner pulls it away.
CAUTION
DISCONNECT SANDER FROM POWER CIRCUIT
To replace the brush-type skirt: (1) Remove abrasive
pad (see ABRASIVE PAD REPLACEMENT). (2) Use
Phillips screwdriver to remove the six retaining screws
(3) Lift the skirt out of housing. (4) Position new skirt
to housing and install the six retaining screws. (5)
Replace the abrasive pad.
SANDING DRYWALL
The Drywall Sander has a unique articulating sanding
head: the head can swivel in multiple directions, allow -
ing the abrasive pad to conform to the work surface
.This enables the operator to sand the top, middle and
bottom of a wall or ceiling joint without changing: his
position.
1. Turn vacuum cleaner switch ON.
2. CAUTION: Wear a respirator approved for
“Dust and Mist”.
3. Turn Drywall Sander switch ON.
4. Position drywall sander lightly against work
surface (apply just enough pressure to align the
sanding head with the work surface).
5. Apply additional pressure to engage the abra-
sive pad to the work surface: while moving the
Sander in an overlapping pattern to smooth the
drywall compound down to a “featheredge’.
Apply ONLY enough pressure to keep the abrasive pad
flat against the work. Excessive pressure can cause
unacceptable swirl marks and unevenness in the work
surface.
Keep the sander in constant motion while abrasive
pad is in contact with the work surface. Use a steady,
sweeping motion. Stopping the Sander (on the work),
or moving the Sander erratically can cause unaccept -
able swirl marks and unevenness in the work surface.
NOTE
Do not allow rotating abrasive pad (Fig.7) to contact
sharp protrusions. Contact with protruding objects
(nails, screws, electrical boxes, etc.), can severely dam -
age the abrasive pad.
ABRASIVE PAD REPLACEMENT
CAUTION
Disconnect Sander from Power Supply.
Grasp the abrasive pad and the sander housing (clamp -
ing the pad to the housing), to prevent pad rotation.
1. Rotate the pad retaining nut, counterclockwise
and remove.
2. Lift off the large metal washer, and the abra -
sive pad.
3. NOTE: When the abrasive pad, is lifted off the
Sander: the abrasive back-up disc is exposed.
Please note that this back-up disc is also cov -
ered with an abrasive material. This abrasive
material is ONLY used to prevent “slippage”
between the back-up disc and the foam backed
abrasive pad, it is NOT suitable for use as a
sanding abrasive. Do not use the sander with -
out a proper abrasive pad installed (to prevent
severe damage to the work).
4. Position new abrasive pad to the back-up disc,
making sure that the center hole in the abrasive
disc is centered on the hub of the back-up disc.
5. Position the large metal washer the retaining
nut to the Sander.
6. Rotate the retaining nut clockwise to hand
tighten (while holding the abrasive pad).
ASSEMBLE FOR LONGER HANDLE (Fig. 6)
Please refer to figure 6.
Insert one tube into the other. Screw.
The extension has been installed.
